What is a C70600 copper nickel tube?
C70600 Pipe also called CuNi 90/10 Pipe, UNS C70600 Pipe, ASTM B466 C70600 Copper Nickel Pipe or Cupro Nickel 90/10 Pipe is ASME B36. 19 M, DIN 86019, EEMUA 144 and MIL-T-16420 copper nickel pipe.C70600 Pipes can stand a test of time, even in the most hostile environments like salty water.The main, wrought copper-nickel alloys chosen for sea water service contain 10 or 30 percent nickel. They also have important additions of iron and manganese which are necessary to maintain good corrosion resistance.C70600 Copper Nickel 10% Alloy is used in applications where resistance to corrosion and stress cracking is important. C70600 Copper Nickel 10% Alloy is known for its moderate strength, weldability and formability.

FAQ
How weldable is C70600?
It is readily weldable using gas tungsten arc welding (GTAW/TIG) and gas metal arc welding (GMAW/MIG) processes. Matching filler metals like ERCuNi or 70-30 CuNi fillers are typically used.
What cleaning methods are recommended for C70600?
Avoid abrasive grit blasting that can embed iron particles. Use non-ferrous brushes, high-pressure water jetting, or chemical cleaning with non-oxidizing acids like hydrochloric or sulfuric acid.
Why is iron content important in C70600?
The iron content (1.0-2.0%) is critical for enhancing erosion-corrosion resistance. It is incorporated into the protective surface film, making it more robust.
Is it magnetic?
C70600 is generally considered non-magnetic, a key advantage for certain naval and scientific applications where magnetic signatures must be minimized.
What are the common product forms available?
It is widely available as seamless tube and pipe (ASTM B466), sheet and plate (ASTM B171), bar (ASTM B151), and welded tube.
